It is provided in the side molding (11) (see FIG. 2).

  In this case, the infrared rays generated from the flame when the gas cooking appliance (2) is used and radiated to the front side of the kitchen cabinet (1) are, for example, in front of the kitchen cabinet (1) as illustrated in FIG. And is detected by an infrared sensor (4) provided in the front operation unit (21) or the side molding (11). And according to this infrared detection state, the operation of the ventilator (3) is controlled by the control device (6) (see FIGS. 4 and 5 described later).

  According to the above, the infrared rays generated from the flame of the gas cooking device (2) and emitted forward and reflected by the worker are accurately detected, and the operation of the ventilation device (3) is automatically performed according to the detection state. You will be able to control.

  The infrared sensor (4) is a position that can detect infrared rays reflected by the operator after being emitted from the flame of the gas cooking appliance (2) and radiated toward the front side of the kitchen cabinet (1). And in a form, it is arrange | positioned at a front operation part (21) or a side molding (11).

  As for the operation control, it is possible to turn on the ventilation operation only when infrared rays are detected, or to control the strength of the ventilation operation based on the magnitude of the detected infrared rays. More specifically, for example, a reference value for switching between on / off and strength may be set in advance, and control may be performed by comparing each reference value with an infrared measurement value.
